How do I access the Russian language keyboard?

I cannot seem to figure out how to access international keyboards in my Nexus 7. In my Iphone, there is a key on the bottom left with a globe on it, and you can press it to switch to the Russian keyboard on the fly, and then press it again to switch back to English. Is it possible to do this on the Nexus 7?
Thanks,
Douglas

For the stock keyboard, go into Settings -> Language & input and select the settings icon next to Android keyboard. Select Input languages at the top of the screen. Uncheck "Use system language". In the Active Input Methods section below, leave English (US) checked, then scroll down and put a check next to Russian.

After that, a Globe button shows up next to the spacebar. Pressing it toggles between all of your selected languages

In case you aren't aware, this also works with the Google voice typing! To do this, select the "Choose input languages" option in the Google voice typing settings, then pick your languages.

Please, help!!! I really need russian keyboard, but nothing works. I tried out many apps, I tried out your suggestion: I can choose many languages for "Google Voice Type", but only English, French and Chinese for keyboard.

I use the swype + dragon keyboard and there are several languages found in the swype settings. I own a Samsung Galaxy S5, what to do is go to settings> language input> swype + dragon> languages> download languages. Hope this helps. I had trouble with it myself at first but is easy to do now that I found it.
